Topic: Authentication problem

Using LDAP backend. I am getting really close to deployment, but run into an issue that I am sure is easy to fix, but I am stumped. Here is what what I did, and why:

- Remove permit_sasl_authenticated from smtpd_recipient_restrictions in /etc/postfix/main.cf I want smtp only being used for external mail delivery- Add "-o smtpd_tls_security_level=encrypt" to smtps in /etc/postfix/master.cf Enforce encryption and authentication on smtps port
